The World's Greatest Sinner is a 1962 American drama film written, directed, and produced by, and starring Timothy Carey. Narrated by voice actor Paul Frees, the film focuses on a frustrated atheist named Clarence Hilliard (later God Hilliard) who rises from an insurance salesman to a powerful figure, but faces consequences from the real God of the Bible, as he alienates his family and friends with his increasing egomania and dictator-like presence. Plot The World's Greatest Sinner introduces a frustrated insurance salesman and his family, Clarence, his wife Edna, his daughter Betty Hilliard, and their son, as well as Clarence's friend, Alonzo. Clarence Hilliard is dismissed by the manager in an insurance company due to Clarence's disregard for the 'scrape and screw' policy. Clarence confesses to Edna that he wants to become more than 'Clarence' and start a political career, but Edna falls asleep. Later, Clarence tells his horse and Alonzo about his ambitions to make humans immortal, and a plan that will make Clarence 'God'. After witnessing an ecstatic crowd at a rockabilly concert, Clarence decides to learn to play the guitar. With the encouragement of Alonzo, Clarence attracts the audiences with his new ideology; that an ordinary person who is now a superhuman being will live forever and become God. Gradually gaining his followers, Clarence proclaims himself 'God Hilliard' and creates a religious cult known as the Eternal Man's Party. In a meeting, the followers consider a few minorities as potential targets for their hatred, but God Hilliard proposes a new way of thinking on "a non-discriminatory basis". Eventually, one of the followers warns God Hilliard that nobody should exert too much power, or one will become a dictator. God Hilliard finances the cult by seducing elderly widows out of their life savings. Meanwhile, Alonzo builds an image of God Hilliard by using false facial hair, trimmed to a soul patch. God Hilliard forms a band at the venue and performs a rockabilly song, with a spoken motif, 'take my hand', and his outrageous stripping. As he relaxes with a snake after his performance, his followers rebel against a man who berates them and threatens to call the police. The followers gather together, shouting "We want God". The followers later cause a riot, which includes destroying objects such as cars and buildings. God Hilliard meets an ex-follower who experiences a mental breakdown since he alienated his family in
